Japan’s new “Aegis” to crack “saturation attack”

Japanese version of Aegis with CEC capabilities
The name “Yuhei” comes from Yuhei Mountain, one of the three mountains in Yamagata Prefecture, Japan. This ship name was used as early as World War II. The latest Moye-class guided missile destroyer belongs to Japan’s latest generation of destroyers. The first ship, the Moyer, was launched in July 2018. It is the latest Aegis heavy-duty air defense missile destroyer under the Japanese Maritime Self-Defense Force. According to the design plan of the new Aegis destroyer 28DDG announced by Japan, the parameters of the ship are as follows: the ship is 170 meters long, 21 meters wide, 12 meters deep, standard draft 6.2 meters, double shaft propulsion, power is 69,000. Horsepower, the highest speed is about 30 knots, the standard displacement is 8,200 tons, the feather black is 10,750 tons, and the Moyer is 10,250 tons. The cost is about 1.6 billion.

It is worth noting that the Yuhei has the same “military revival” as the names of the six Aegis ships that were previously in service. The four King Kong-class destroyers that were first served, in addition to the No. 3 ship Miaogao (When the World War II wonderful heavy cruiser), the No. 4 ship Bird Sea (the No. 4 ship of the Kaohsiung heavyweight cruiser), the other two King Kong and Kirishima Both used the name of the ship of the World War II King Kong battleship. The two Ai-class (also known as the King Kong) destroyers after the King Kong class, the ship name was inherited from the No. 2 ship Ai 宕 of the Kaohsiung-class heavy cruiser, and the foot of the wonderful senior cruiser.

From the appearance point of view, the Yuhei and the previous type of 舰-class hull did not change much, but it improved in three aspects: First, it strengthened the cooperative combat capability (CEC)—in fact, it was a network-centric warfare—a place The information discovered by the platform can realize the real-time sharing of the entire fleet and even the friendly forces; the second is to install the AN/SPQ-9B X-band radar, which can deal with the stealth small targets of the sea-skiing flight; the third is to strengthen the anti-submarine capability and install the AN/SQR- 20 tow the array sonar system. On the whole, after the upgrade of the avionics system, the comprehensive combat capability of the Moyer class has almost been upgraded to the level of the American Ali Burke Level FlightIIA, and the corresponding “Aegis” system should be the Japanese version of the baseline type 9. Compared with the Aegis Baseline 7.1, which is equipped with the Ai-class, the Baseline 9 upgrades the data processing system and adds the “Cooperative Operations Capability” (CEC), equipped with X-band high precision for close sea and air search. The radar, combined with the latest multi-functional towed array sonar system, has achieved superior super-horizon air defense capability and ballistic missile interception capabilities.

In terms of weaponry, the Moyer class is equipped with a 127 mm Mk-45 mm gun, two MK-15 dense array short-range defensive weapon systems, and two 68-type torpedo tubes (with six torpedoes). In front of the bridge and behind the chimney, the Moyer class is equipped with a 96-unit Mk-41 vertical launch system that can carry a variety of missiles, including SM-2ER, SM-3B and SM-6, for a total of 96. In addition, the Moyer class can also be equipped with a SH-60K anti-submarine helicopter. It can be said that the Moyer class has the strongest combat power in the current eight ships of the same class in Japan because it is equipped with the latest “Aegis” system that can locate the other ballistic missiles or fighters and transmit the data to the United States and other allies.

In addition, the biggest selling point of Yuhei is equipped with CEC system. With this system, the ship’s “Aegis” system equipped with SPY-1D phased array radar can receive target data from the E-2D “Advanced Hawkeye” early warning aircraft, so that SM can be launched. -6 long-range ship-to-air missiles to combat single or multiple targets outside the scope of shipborne radar detection to achieve the effect of “bringing cattle across the mountain”. This combat capability is also the dream of the Japanese Maritime Self-Defense Force. To this end, Japan is also preparing to receive four US E-2D early warning aircraft by 2020. Therefore, after the service of the Moyer and Yuhei, the maritime air defense and anti-missile capabilities of the Japanese Maritime Self-Defense Force will undoubtedly increase significantly.

8 “Aegis” teams assisted the US military

The so-called “Aegis” ship refers to a ship equipped with the “Aegis” integrated combat system developed by the United States, thus giving the ship a powerful air defense, anti-ship, anti-submarine and electronic warfare capabilities. Its typical feature is that the high-performance four-sided phased array radar and the interceptor missiles that it carries form a strong regional air defense capability. This is the US Navy’s famous DDG-51 Ali Burke-class guided missile destroyer. Japan is a country that introduced the US “Aegis” system earlier. At present, the Maritime Self-Defense Force has four King Kong-class “Aegis” ships and two Ai-class ships. It is about to serve two Moyer-class ships, especially the six ships that served earlier. The “Aegis” ship will be upgraded to have missile defense capabilities by the end of 2019, so there is a new enhancement in its combat power. After the service of Yuhei, the “Aegis” ship of the Japanese Maritime Self-Defense Force will reach 8 ships, so that the four escorts of the Japanese Maritime Self-Defense Force can be assigned to two, so that they can intercept ballistic missiles. The ability to be further improved.

So what is the combat capability of Yuhei? It can be said that among the Japanese Maritime Self-Defense Forces, the upcoming Yuhei and Moyer are the most powerful Aegis ships with the most missile defense capability. The SM-3B missiles are equipped with a range of about twice the range of the missiles previously carried. It can carry out interception operations in distant seas. More importantly, the Moyer class can share the position information of enemy missiles and fighters with the US Navy in real time after being equipped with the CEC system, that is, it can use the US Aegis ship, the E-2D early warning aircraft, the P-8A anti-submarine aircraft, and Satellite intelligence, the Japanese “Aegis” ship can still carry out missile interception operations without itself finding the target. To this end, the Japanese Defense Ministry also learned the configuration of the US military, and purchased four E-2D early-warning aircrafts installed by the United States for the Maritime Self-Defense Force from the United States, thus achieving intelligence networking with the US military.

Cooperative combat capability
After talking for a long time, what is CEC? This is the networked operational command developed by the US Navy since 1987, based on the C3I (the first letter of the command, control, communications, and intelligence systems) command automation technology system to strengthen the maritime air defense (anti-missile) combat capability. The most important feature of the control communication system is that it can use the network technology to connect the radar, fire control system, weapon system and shipborne early warning aircraft on each warship in a carrier strike group (there are also some stealth fighters, drones, and high altitudes in the future). Monitoring airships, etc.) to achieve real-time operational information sharing, enabling each combat platform to grasp the battlefield situation and enemy target trends in a timely manner, and greatly enhance their comprehensive operational capabilities.

Of course, Japan’s mission to build the Moyer-class Aegis is not only missile defense, but also fleet air defense and anti-submarine warfare. Its CEC system can play a role in all aspects. According to the data comparison, the Moyer-level displacement has increased by 5% compared with the Ai, and has become Japan’s strongest sea battleship. Moreover, Yuhei has a 96-unit Mk-41 vertical launch system with SM-2ER long-range air defense missile, SM-3B anti-missile interceptor, XASM-3 supersonic anti-ship missile, etc., especially the maximum range of SM-3B. It is 500 kilometers high and has a high altitude of 160 kilometers. It has strong air defense and anti-missile capabilities. The planned SM-6 missile not only has the super-horizon capability of the SM-2ER, but also a missile with air defense, anti-missile and anti-ship capabilities. Therefore, the Yuhei is one of the strongest anti-aircraft and anti-missile ships in Asia. The ship can be called the “Asian Sea Three Ships” together with the Sejong King of Korea and the Type 055 destroyer of China.

After the future Moye and Yuhei service, due to the installation of the CEC system, this system can also achieve seamless connection with the Japanese land-based “Aegis”, plus the E-2D early warning aircraft and the “Navy Integrated” The Air Defense Fire Control System (NIFC-CA) will provide more information support for Japan’s own missile defense. In particular, through the CEC system, the Japanese Maritime Self-Defense Force’s warships can also be networked with US Navy warships and early warning aircraft in the future, further embodying the military value of the US-Japan alliance. Although the Japanese Maritime Self-Defense Force currently claims to be equipped with CEC systems only on these two warships, it does not rule out the possibility of having CEC systems on the other six Aegis ships and other warships after the test, thus allowing Japan to Truly tied to the US military, it gives it greater confidence to intervene strongly in Asia-Pacific affairs. But what needs to be vigilant is that with the CCE “power multiplier”, the Japanese Maritime Self-Defense Force will weaken China’s anti-ship ballistic missiles and cruise missiles’ “saturation attack” deterrence to a certain extent, thus making it resurrected militarism. The dream goes farther and farther!
